It seems to behave as advertised when SCROLLBARS is assessed in a subclass:

public ot
ot=createobject('mf')
ot.addobject('c1','container')
c1=ot.c1
c1.visible=.t.
c1.height=600
ot.show

define class mf as form
scrollbars=3
visible=.t.
enddefine

Appologies for not trying this first!

>When I create a form and set SCROLLBARS to 3 through the visual designer, and then add a container and make its dimensions larger than the form's, the scrollbars appear (as expected).

>But, when I do it in a PRG, the scrollbars do not appear. Here's the code - all assistance appreciated!

public ot

>ot.addobject('c1','container')
>c1=ot.c1
